Fig. 5'is a transverse sectional'view taken on line '5- 5 of- Fig.4.

Fig. 6 is a fragmentary enlarged sectional view taken on' line 6'6 of Fig. '5. i :0 Referring particularly to Fig. 1 of the drawings, the'numeral' 1O designates'a'frame of rectangular shape in which three hollow drums .11, 1-2 and 13 are rotatively'm'ounted in horizontal alignment. Flanges 11,- 12' and 13. tend to keep the air away from the vacuum created by drums 11, 12 and 13, respectively, above the periphery of the said rotary drums. Stud shafts 14are' mounted rigidly on' the leftend of the drums 11, 12 and 13 and are rotatively j ournaledin bearing members 15,'mo1'1nted in the left-side 16 of the frame 10. A vertically extending par- 1 tition 17 is disposed in the frame in spaced relation to the right side '18 of the said frame.

ends Ofith drums 11, 12 and 113,'and' are disposed through apertures inithe partition 17 Shafts 19 are rigidly attached to thef'i'ight outer ends in bearin s 22 'on the side 18 of the frame '10 and are 1ournaledat their other end portions in aperturesin'the partition 17. The shafts 21 are equally spaced between the shafts 19 of the adjacentrollers. Gears 23 are rigidly mounted'on the 'shafts 19'of the drums 1'1, 12 and -13 and aremeshedwith idler gears 24-m0un-tedon theshafts 21. The gears '24 are disposed between each'of the gears 23 of the drumsfor the purpose of causing the rotation of all the drums to be in one and the samefdirection. L

A gasoline engine- 25 is mounted on the base 25' of the frame 10 and-is provided with s a shaft 26 havinga pinion 27 thereon in mesh with the lowermost gear 23.-

- The'engineshaft 26 is provided witha second pinion meshin with a bevel gear 51 fixed on-a vertical-sha 52 rotatively mounted in the frame 10 by engaging a thrust bearing 53, and a helicopter propeller 54 is-fixed on the lower end ofthe shaft 52. This propeller forces the machine upwards. The engine 25 is of the type having exhaust pipes 57 discharging exhaust gas. Pipes 56 connect with the pipes 55,'and have a plurality of downwardly directed nozzles 57, -Exhaust gas discharging from these nozzles forces the machine upwards. It is pointed out that upon a proper regulation of the speed of the engine 25, the machi aie canmain- 'tain various speeds in the air duifing flight.

In the modified form of my invention shownin Figs. 4 and 5 the frame 10 is provided with three pairs of laterally disposed cleats .28 and 29 .both cleats being positioned in superimposed relationadjacent the drums and spaced apart by blocks 30 mounted on the sides of the frame 10. The cleat 29 extends from one side of the frame 10 to the artition 17 and the cleat 28 extends'from si e to side of the frame. A shaft "32 is journaled at its 43, respectively. The shafts 41, 42 and 43 are journaled in bearing members 44, 45 and 46, mounted on the outer cleat 28 and the outer extremities of the shafts 41, 42 and 43 are provided with propeller members 47, 48 and 49, respectively. It should be understood that the propellers may be rotated when the drums are rotated byan operative driving connection between the gear 23 and the gear 33, the latter gear being slidably mounted on the square section 32 of the shaft 32 so as to be able to be moved into and out of mesh with the gear 23 as desired. It should also be understood that each drum is provided with a set of three propellers mounted and operatively connected to the driving mechanism as described above.

The nozzles 57 are provided with end couplings 58 engaging flexible exhausts 59. C01- lars 60 are fixed on the exhaust 59. and rods 61 and 62 are disposed between the collars and project towards each other. The rods 61 are formed with right hand threads, and rods 62 with left hand threads, and tubular connectors 63 threadedly engage these rods. The connectors 63 may be rotated for changing the distances between the flexible exhausts 59 for causing them to bend and thus changing their directions of discharge from truly vertical to slight inclinations. It will be found that the operation of the exhausts are more efiicient in slightly inclined positions.

It should be understood that rockets and superheated steam may be also used for forcing the machine upwards. 4

In the operation of my invention the pro- I pellers 47. 48 and 49 when rotated produce a current of air which is directed against the drums 11, 12 and 13, substantially at right angles thereto. If there is a natural. current of air in motion, then the device is so 'positioned so as to have the natural current of air combined with the artificial current of air produced by the propeller. When there is a sufliciently strong natural current of air the artificial current is not necessary and if desired the propellers may be rendered inoperative by disengaging the gears 23 and 33 as above set forth. The hollow cylinders or drums rotate at a very high speed preferably 200 R. P. M. and the rotation of the propellers'may be predetermined by the selection of suitable gears. The resultant of the air forces set up around the drums and the perpendicular force developed by the propellers is an upwardforce which tends to urge the device upwardly against the force.

of gravity. While I have shown and described the preferred embodiment of my invention, it is to be understood that I do not limit m self to the precise construction herein disc osed and the right is reserved to all changes and modifications coming within the scope of the helicopter upwards into the vacuum created by the said cylinders.
